Not quite 'King's Liverpool'. The regiment disappeared in 1958 when amalgamated with the Manchesters. The AA version of the 1950 size badge was still not officially available in 1959 - in fact he first documented use (CCN) was in 1963 for the 5th TA Bn - which survived up to 1967.
The LUOTC almost certainly wore it from then too - but they had a new Pattern designation in 1971 when it appeared without stippling / seeding.
